This is lesson five of a 9-lesson module. Activity explores the effects of climate change on different parts of the Earth system and on human well-being: polar regions, coral reefs, disease vectors, extreme weather, and biodiversity.

Teaching Tips

Activity could easily be a great example of a "flipped" classroom experience in which students complete this at home in preparation for a hands-on demonstration or investigation the next day in class in which they are putting their understanding to the test.

Activity covers a lot of different concepts. Educator may want to take some extra time to focus on the key ideas, so students are not overwhelmed with information in a short amount of time.

Activity is part of what is essentially an online textbook.
Perhaps best used in conjunction with the other 8 lessons.

About the Science

Activity covers a number of scientific topics, from how climate change will increase extreme weather, to how climate change could alter the functioning of coral reefs. Climate modeling tools and visualization tools both are embedded within this lesson to enhance the user's experience and bring real data into the activity.

Comments from expert scientist: The scientific strength in explaining what models are is low. The explanations of a scientific model and a climate model are vague and unclear. The website however did a fairly good job explaining the IPCC scenarios and storylines. The information is accurate, but they need to explain how these scenarios are related to the climate models.

About the Pedagogy

Five key ideas are listed across the top menu bar for lesson five in this series. Embedded within each key idea are links for supporting materials, such as models and visualizations to engage students throughout the lesson and help them understand concepts.

Interactive design allows students to manage at their own pace.

Students are guided through a series of slides and asked questions to build mastery and understanding of content.

Activity includes an interactive climate tool that students use to answer questions as they cover different topics.

Technical Details/Ease of Use

All simulations, animations, and visualizations embedded within this lesson worked well and were easy to read.

Disciplinary Core Ideas: 4

MS-ESS2.D3:The ocean exerts a major influence on weather and climate by absorbing energy from the sun, releasing it over time, and globally redistributing it through ocean currents.

MS-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.

MS-LS2.A1:Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.

MS-LS2.C1:Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.

MS-P6.3:Construct a scientific explanation based on valid and reliable evidence obtained from sources (including the students’ own experiments) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.

MS-P6.6:Apply scientific ideas or principles to design, construct, and/or test a design of an object, tool, process or system.

MS-P7.3:Construct, use, and/or present an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.

High School

Performance Expectations: 1

HS-ESS3-5: Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth systems.

Disciplinary Core Ideas: 8

HS-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.

HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.

HS-ESS3.D1:Though the magnitudes of human impacts are greater than they have ever been, so too are human abilities to model, predict, and manage current and future impacts.

HS-LS2.A1:Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. Organisms would have the capacity to produce populations of great size were it not for the fact that environments and resources are finite. This fundamental tension affects the abundance (number of individuals) of species in any given ecosystem.

HS-LS2.C1:A complex set of interactions within an ecosystem can keep its numbers and types of organisms relatively constant over long periods of time under stable conditions. If a modest biological or physical disturbance to an ecosystem occurs, it may return to its more or less original status (i.e., the ecosystem is resilient), as opposed to becoming a very different ecosystem. Extreme fluctuations in conditions or the size of any population, however, can challenge the functioning of ecosystems in terms of resources and habitat availability.

HS-LS2.C2:Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species.

HS-LS4.C4:Changes in the physical environment, whether naturally occurring or human induced, have thus contributed to the expansion of some species, the emergence of new distinct species as populations diverge under different conditions, and the decline–and sometimes the extinction–of some species.

HS-LS4.C5:Species become extinct because they can no longer survive and reproduce in their altered environment. If members cannot adjust to change that is too fast or drastic, the opportunity for the species’ evolution is lost.

Cross Cutting Concepts: 7

Patterns, Cause and effect, Systems and System Models, Energy and Matter, Stability and Change

HS-C1.4:Mathematical representations are needed to identify some patterns

HS-C2.2:Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.

HS-C4.3:Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions—including energy, matter, and information flows—within and between systems at different scales.

HS-C4.4:Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.

HS-C5.2:Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system.

HS-C7.1:Much of science deals with constructing explanations of how things change and how they remain stable.

HS-C7.2:Change and rates of change can be quantified and modeled over very short or very long periods of time. Some system changes are irreversible.

Developing and Using Models, Analyzing and Interpreting Data, Using Mathematics and Computational Thinking, Constructing Explanations and Designing Solutions, Engaging in Argument from Evidence

HS-P2.1:Evaluate merits and limitations of two different models of the same proposed tool, process, mechanism or system in order to select or revise a model that best fits the evidence or design criteria.

HS-P4.1:Analyze data using tools, technologies, and/or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims or determine an optimal design solution.

HS-P5.3:Apply techniques of algebra and functions to represent and solve scientific and engineering problems.

HS-P6.2:Construct and revise an explanation based on valid and reliable evidence obtained from a variety of sources (including students’ own investigations, models, theories, simulations, peer review) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.

HS-P7.1:Compare and evaluate competing arguments or design solutions in light of currently accepted explanations, new evidence, limitations (e.g., trade-offs), constraints, and ethical issues
